This work aimed to verify compliance and validate the performance of two-dimensional gas chromatography coupled to mass spectrometry in different laboratories by monitoring probe metabolites in exhaled breath.

Two-dimensional gas chromatography (GC×GC) methodology, with dedicated sample preparation techniques, has been applied to investigate lipid fractions - total fatty acid profile and minor lipid components.

Two procedures are described for the determination of non-volatile hydrocarbons according to DIN H53 (ISO 16703) using Clarity software by DataApex.

In the first, part we will summarize why GC×GC has not yet become established in the pharmaceutical field. In the second part, we will present how GC×GC-HRMS was used to investigate the active API.
